示例1: parseValue

import org.eclipse.milo.opcua.stack.core.types.builtin.Variant; //导入依赖的package包/类
public static DataValue parseValue(Object value, Marshaller marshaller) {
    JAXBElement<?> jaxbElement = JAXBElement.class.cast(value);

    StringWriter sw = new StringWriter();

    try {
        marshaller.marshal(jaxbElement, sw);
    } catch (JAXBException e) {
        LOGGER.warn("unable to marshal JAXB element: " + jaxbElement, e);
        return new DataValue(Variant.NULL_VALUE);
    }

    String xmlString = sw.toString();
    try {
        XmlDecoder xmlDecoder = new XmlDecoder(new StringReader(xmlString));
        Object valueObject = xmlDecoder.decodeVariantValue();

        return new DataValue(new Variant(valueObject));
    } catch (Throwable t) {
        LOGGER.warn("unable to parse Value: " + xmlString, t);
